Title: Motorized ball toy with improved torque
Inventor: CHRISTEN RICHARD P
IPC: A63H33/00
Filed: 1993-03-08
Abstract: Abstract of the Disclosure The invention provides a motorized ball toy with improved torque, traction and operating stability.  The ball toy moves in response to internal motive power provided by a battery and motor mounted within the ball.  The ball has two hemispheres which are joined together along their respective peripheral edges.  A central shaft extends diametrically across the ball and is secured at each end by a shaft mount on the interior of each of the hemispheres.  One of the shaft mounts releasably engages the central shaft and the other shaft mount nonrotatably engages the central shaft.  A motor drive frame within the ball is supported on the central shaft.  The drive frame is rotatable about the central shaft 360°.  A motor on the drive frame imparts relative rotation between the drive frame and the central shaft which, in turn, drives the ball.  An inert mass in the form of a zinc weight is attached to the drive frame at a predetermined distance from the central shaft to increase the torque imparted by the motor.  The zinc weight is preferably curved and mounted at the extremity of the drive frame closest to the exterior wall of the ball, thereby maximizing the moment of inertia of the drive frame.

IPC: C07D303/04
Filed: 1992-06-25
Abstract: Alkenes can be epoxidised with hydrogen peroxide using a homogeneous heavy metal catalyst, but discharge of spent reaction mixtures releases the heavy metal in the environment. The problem can be ameliorated by selecting a heterogeneous catalyst system comprising a tungsten-containing heteropolyacid supported on selected Group IIa, IIb, IIIb, IVa or IVb inorganic supports or on a strong basic resin, which catalyst has either been calcined after impregnation or in the impregnation stage an alcoholic solution of the heteropolyacid is employed and by employing a nitrilo or oxygenated polar solvent reaction medium. A number of preferred heteropolyacids satisfy the empirical formula M3/nPWwMO12-wO40 in which w represents an integer of at least 1, M represents a counterion and n its basicity. Preferred supports include activated alumina, calcined at 400 to 600· C and cross-linked quaternary ammonium-substituted polystyrene resins. The most preferred catalysts are made by impregnating an inorganic support with a methanol solution of the heteropolyacid to a desired loading of active material on the support and subsequently calcining the loaded support at 400 to 600· C. Preferred reaction media include acetonitrile and tertiary butanol.

Title: A system for extinguishing an oil well subjected to very high pressure ons
Inventor: FERRAYE JOSEPH
IPC: A62C3/06
Filed: 1992-05-04
Abstract: The invention describes a system for extinguishing fires in oil wells subjected to very high pressures, and cooling of the surrounding ground. The base of the system is, for example, of conical shape resembling a volcano. The flames are stifled by introducing a non-flammable gas (e.g. nitrogen or liquid carbon dioxide) or water into the system through holes (4a, 4b) in the conical section. The turbulent propagation of this gas, achieved by using angle connectors in the system, occurs in the same direction as the flames and is intensified in an upward direction by the conical shape of the system. The outlet via the crater (1) is a form of eruption encompassing all the flames, and nitrogen is directed downward to cool the surrounding ground.

Title: Process for the obtention of a biological adhesive made of concentrated coagulation factors by acidic precipitation
Inventor: BUI-KHAC TRUNG
IPC: C07K14/745
Filed: 1994-01-18
Abstract: The present invention relates to a process of making a concentrate of coagulation proteins starting with whole human or animal plasma. This concentrate is used as a biological adhesive when extemporaneously mixed to thrombin. The concentrated proteins include mostly fibrinogen, fibrin stabilizing factor (factor XIII) and fibronectin. The claimed process has the advantage of being short of execution while providing an excellent yield of coagulable proteins. No protease inhibitor has to be added during the process. The process involves steps of acidic precipitation in presence of amino-6 hexanoic acid which prevents co-precipitation of plasminogen with the desired coagulable proteins. The proteins so obtained are very stable after reconstitution in water for at least 24 hours at room or body temperature. After mixing with thrombin, the adhesive shows excellent strength arid biocompatibility.

Abstract: A telecommunication device for the deaf (12, 14, 16, 20, 22, 24, 26, 28) is designed to operate under an enhanced TDD communication protocol. The TDD (12, 14, 16, 20, 22, 24, 26, 28) is capable of communicating with conventional TDDs operating under normal Baudot/Weitbrecht communications, but is also capable of communicating with a similarly enhanced TDD utiliz-ing an enhanced protocol with a faster data transfer rate. The enhanced TDD is capable of signaling to another remote TDD through the use of a synchronization character that it is capable of enhanced TDD communications. If a similar synchronization character is received from the remote station, both TDDs can then switch to enhanced TDD communication with its advantages of speed and enlarged character set. The synchronization character is especially designed so as not to interfere with the operation of a conventional TDD which might receive the character and also to be sufficiently distinctive so as to be capable of definite re-ception by enhanced TDD machines with minimum error.

Title: Shape of a desk top, largely, for the integration of a personal computer system into the office environment
Inventor: LOHSE ALBRECHT K
IPC: A47B83/00
Filed: 1994-02-08
Abstract: The personal computer or computer terminal, being a useful addition to the office work environment, represents an intrusion into that environment. Sometimes the computer is simply added to the environment upon traditional furniture.          Some designs which attempt to integrate the computer into the office, with varying degrees of success, have emerged. This newly invented design addresses the needs of a person utilizing a computer while also carrying out traditional office work.          Rather than a traditional desk which has only one working edge for its user, the new design has two edges. The design offers two distinct working regions on a substantially flat surface which may be accessed by simply swivelling in a chair.          Computer with peripherals are placed into one region, while the other region is available for traditional office work. A convenient interaction or overlap region exists between these two distinct regions. This new design, better than any previous, recognizes the ergonomics of the utilization of computers and terminals in the modern office environment. The preferred embodiment of this innovative design is a rectangle with a generous "V" notch cut into the middle of one of the long sides. A prototype has been built. It works better than expected.
